pedit

pedit is a command line utility that helps with automation of editing configuration files.

Features

• Edits are idempotent which makes the tool suitable for use in administration script and systems like Puppet or Chef.
• Ensure line in a text file is present or absent.
• Ensure key-value pair in a text file is present or absent.
• Key-value pairs can also be defined multiple times with different values (--multikey).
• Support for relative placement of lines or key-value pairs in respect to existing lines in the text file.
• Regular expressions are used for matching values in the files.
• Check mode in which the tool will signal with exit status if change was required without performing any changes.
• Show changes applied or would be applied in diff style.
• Tested on MacOS as well as Windows.

Example usage

Ensure that ssh_config file contains key StrictHostKeyChecking set to value yes; if the key is absent put the pair before line containing UserKnownHostsFile.

pedit --in-place ~/.ssh/ssh_config --diff line-pair --separator " " "StrictHostKeyChecking yes" present relative-to "UserKnownHostsFile" before
